On its own, that is not a shocking revelation. Many adults who have have professional relationships eventually develop romantic feelings for one another.

But for Stubblefield, now 45, the situation led to criminal charges; the now-34-year-old man she had the relationship with, known as D.J., had such severe cerebral palsy that he couldn’t speak or go to the bathroom on his own. The state declared him to have the mental capacity of a toddler, though Stubblefield disagrees with that assessment.

Earlier this month, a jury convicted her of sexually assaulting D.J. after deliberating for just three hours, according to NJ.com. She’ll be sentenced on November 9 and could go to state prison for 10 to 40 years.

She used a controversial method called facilitated communication (F.C.) with D.J. It’s controversial because there are differing opinions on whether F.C. is actually effective.

Many experts have debunked the technique, calling it the ideomotor effect, meaning a person’s personal beliefs trigger unconscious movement, much like movement on a Ouija board.

Still, Stubblefield believes the method provides a way for the severely disabled to communicate. When she met D.J., she used F.C., first encouraging him to point to objects, and gradually working up to the point where he could spell words on a hand-held keyboard to have conversations. D.J. couldn’t operate the keyboard on his own, so Stubblefield would support his arm and help guide him when necessary.

After three decades of silence, it seemed D.J. was finally able to communicate with the outside world.

But the family’s elation quickly turned to horror on Memorial Day 2011 when Stubblefield announced that she and D.J. were in love.

After repeatedly telling Stubblefield to stay away from D.J., and her continued attempts to get in contact with him, P. and Wesley alerted the authorities to the sexual relationship between Stubblefield and D.J.

The trial began in September, and the prosecution described Stubblefield as a respected professor who took advantage of a severely disabled man to satisfy her sexual desires and further her career, NJ.com wrote.
